Abstract

A diesel engine with soot burn-off filter and a method for the ignition of soot burn-off filters in the exhaust line of diesel engines by means of hot exhaust gases is described, which is based on the fact that for an essentially constant engine speed the exhaust gas temperature is increased by increasing the engine load. The engine load is increased by switching on additional devices normally already present in the motor vehicle, such as retarder, engine brakes or vehicle brakes. The method ensures reliable filter cleaning at all times, even in the case of predominantly partial-load operation.

Verfahren zum Zünden von Rußabbrennfiltern und Dieselmotor mit RußabbrennfilterProcess for igniting soot burn-off filters and diesel engines with soot burn-off filters

Gegenstand der Erfindung ist ein Verfahren zum Zünden von Rußabbrennfiltern im Abgasstrang von Dieselmotoren durch heiße Abgase sowie ein Dieselmotor mit Rußabbrennfilter.The invention relates to a method for igniting soot burn-off filters in the exhaust system of diesel engines through hot exhaust gases and a diesel engine with a soot burn-off filter.

Zur Verringerung der Partikelemission von Dieselmotoren werden diese Partikel im Abgasstrang mittels besonderer Filtereinrichtungen aus dem Abgasstrom herausgefiltert. Um ein Verstopfen der Filter und damit die Betriebsunfähigkeit des Motors zu vermeiden, werden die Filter in regelmäßigen Abständen durch Abbrennen des auf ihnen angesammelten Rußes regeneriert, weshalb die Filter auch den Namen Rußabbrennfilter tragen. Die Zündung kann entweder durch ein elektrisches Heizsystem erfolgen (z.B. DE-OS 26 55 932), im allgemeinen wird aber das Filter im Abgasstrang so angeordnet, daß die Zündung durch die heißen Abgase erfolgen kann (z.B. DE-OS 27 50 960).To reduce the particle emissions from diesel engines, these particles are in the exhaust system by means of special Filter devices filtered out of the exhaust gas flow. About clogging of the filter and thus the inability to operate To avoid the engine, the filters are periodically burned off by burning off the accumulated on them Soot regenerates, which is why the filters are also called soot burn-off filters. The ignition can either be done by an electrical heating system (e.g. DE-OS 26 55 932), but in general the filter is in Exhaust line arranged so that ignition can take place through the hot exhaust gases (e.g. DE-OS 27 50 960).

Es hat sich jedoch gezeigt, daß im Teillastbetrieb die Abgastemperatur zur Zündung de^ Rußabbrennfilters häufig nicht ausreicht, so daß das Rußabbrennfilter zunehmend verstopft.It has been shown, however, that in partial load operation the exhaust gas temperature for igniting the soot burning filter often occurs is insufficient, so that the soot-burning filter becomes increasingly clogged.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Dieselmotor mit Rußabbrennfilter sowie ein Verfahren zum Zünden eines Rußabbrennfilters zu finden, das einfach ist und bei dem im allgemeinen auf die bei dem Betrieb von Fahrzeugen mit Dieselmotoren normalerweise vorhandenen Einrichtungen zurückgegriffen werden kann.The invention is therefore based on the object of providing a diesel engine with a soot burning filter and a method for To find ignition of a soot burn-off filter that is simple and that is generally based on the operation of Vehicles with diesel engines normally available facilities can be used.

Diese Aufgabe wird durch den in den Patentansprüchen beschriebenen Motor sowie das Verfahren gelöst. Die Erfindung beruht also darauf, die Abgastemperatur durch Erhöhung der Motorbelastung bei im wesentlichen gleichbleibender Motordrehzahl bzw. Geschwindigkeit zu erhöhen.This object is described by the one in the claims Engine as well as the procedure solved. The invention is based on increasing the exhaust gas temperature to increase the engine load while the engine speed or speed remains essentially the same.

Einrichtungen, mit denen sich die Motorbelastung erhöhen läßt, sind bei Fahrzeugen mit Dieselmotoren bereits vorhanden. Es handelt sich dabei um bekannte Einrichtungen wie Retarder oder Drosselklappen in der Auspuffanlage (Motorbremse), die in größeren Fahrzeugen serienmäßig vorhanden sind oder um die Fahrzeugbremse. Erreicht die Filterbelegung einen bestimmten vorgegebenen Wert, der sich durch einen bestimmten Gegendruck vor dem Filter bemerkbar macht,Devices with which the engine load can be increased are already available in vehicles with diesel engines. These are known devices such as retarders or throttle valves in the exhaust system (engine brake), which are standard in larger vehicles or to the vehicle brake. Reaches the filter occupancy a certain predetermined value, which is noticeable by a certain counter pressure in front of the filter,

c
so wird der Retarder, die Motorbremse oder eine sonstige Bremse zugeschaltet. Die Motorbelastung erhöht sich dadurch, die Abgastemperatur steigt und führt zur Zündung des Rußabbrennfilters. Statt den Zeitpunkt der Erhöhung der Motorbelastung von der Filterbelegung abhängig zu machen, kannc
so the retarder, the engine brake or another brake is switched on. The engine load increases as a result, the exhaust gas temperature rises and leads to the ignition of the soot combustion filter. Instead of making the time of the increase in the engine load dependent on the filter occupancy, you can

auch eine Zeitschaltung verwendet werden, mit der die genannten Einrichtungen zur Erhöhung der Motorbelastung in vorgegebenen Intervallen in Betrieb genommen werden, jedoch ist eine solche Zeitregelung nicht so günstig, da sie nicht auf die individuelle Filterbelegung Rücksicht nimmt. Die Dauer der Erhöhung der Motorbelastung kann durch den Abgasgegendruck des Filters (Strömungswiderstand) gesteuert werden, möglich ist jedoch auch eine Zeitsteuerung anhand einmalig für den entsprechenden Motor- und Filtertyp ermittelter Werte. Die Motordrehzahl bzw. die Geschwindigkeit des Fahrzeuges soll natürlich durch das Zuschalten der genannten Einrichtungen zur Erhöhung der Motorbelastung nicht beeinträchtigt werden. Das kann man durch an sich bekannte Einrichtungen zur Einhaltung einer gleichbleibenden Fahrtgeschwindigkeit ("Tempomat") erreichen. Jedoch ist die zuästzliche Verwendung solcher Einrichtungen nicht erforderlich, da der Fahrer bei Absinken der Fahrzeuggeschwindigkeit instinktiv mehr Gas gibt um das Absinken der Geschwindigkeit bzw. der Motordrehzahl auszugleichen. Durch eine geeignete Schalteinrichtung ist an sich selbstverständlich bei der Verwendung von Einrichtungen zur Einhaltung einer gleichbleibenden Fahrgeschwindigkeit ("Tempomat") dafür zu sorgen, daß bei tatsächlichen Bremsvorgängen der Tempomat abgeschaltet wird. Auch derartige Schaltungen sind bekannt und üblich. Die Verwendung von zwei Druckfühlern vor und hinter dem Rußabbrennfilter ist besonders vorteilhaft, da durch die dadurch mögliche Differenzbildung der tatsächliche Strömungswiderstand des Rußabbrennfilters unabhängig von der Belastung des Motors besonders genau ermittelt werden kann.a timer can also be used with which the devices mentioned to increase the engine load be put into operation at predetermined intervals, but such a time control is not as favorable as it does not take into account the individual filter assignment. The duration of the increase in the engine load can can be controlled by the exhaust gas back pressure of the filter (flow resistance), but one is also possible Time control based on values determined once for the corresponding motor and filter type. The engine speed or the speed of the vehicle should of course be increased by switching on the mentioned devices the engine load are not impaired. This can be done by means of compliance facilities that are known per se a constant driving speed ("Tempomat"). However, it is an additional use Such devices are not required, since the driver instinctively when the vehicle speed drops give more gas to compensate for the drop in speed or engine speed. Through a suitable Switching device is a matter of course when using devices to comply with a constant driving speed ("Tempomat") for it to ensure that the cruise control is switched off when the brakes are actually applied. Such circuits are also known and common. The use of two pressure sensors in front of and behind the soot burn-off filter is particularly advantageous, because of the difference formation possible as a result, the actual flow resistance of the soot burn-off filter can be determined particularly precisely regardless of the load on the engine.

In der Abbildung wird schematisch ein Dieselmotor mit Rußabbrennfilter gezeigt. Ein Vierzylinderdieselmotor 1 ist mit einem Rußabbrennfilter 2 im Abgasstrang 3,4 versehen. Vor und hinter dem Filter 2 sind Druckfühler 5 und 6 zur Ermittlung des Strömungswiderstandes des FiI-ters 4 angebracht, die über die Leitungen 7 und 8 mit einer Betätigungseinrichtung 9 für eine im Auspuffrohr angeordnete Drosselklappe 10 in Verbindung stehen. Übersteigt der durch die Druckfühler 5 und 6 ermittelte Strömungswiderstand einen vorgegebenen, von der Art des verwendeten Filters und des Motortyps, abhängigen und für jeden Motor- und Filtertyp einmalig zu ermittelnden Wert, so wird die aus Betätigungseinrichtung 9 und Drosselklappe 10 bestehende Motorbremse aktiviert, die Motorbelastung steigt an und der Ruß auf dem Rußabbrennfilter brennt ab. Die Dauer der Betätigung der Motorbremse, die zum Abbrennen des Filters ausreicht, ist für jeden Motortyp ebenfalls einmalig zu ermitteln, kann aber auch, insbesondere bei der Verwendung von zwei Druckfühlern bei Benutzung einer Motorbremse oder bei der Verwendung eines Retarders oder der Fahrzeugbremse direkt durch den Abgasgegendruck vor dem Filter individuell gesteuert werden.The figure shows a schematic diagram of a diesel engine with a soot burn-off filter. A four cylinder diesel engine 1 is provided with a soot burn-off filter 2 in the exhaust line 3, 4. There are pressure sensors 5 in front of and behind the filter 2 and 6 for determining the flow resistance of the fiI-ters 4 attached via the lines 7 and 8 with an actuating device 9 for a throttle valve 10 arranged in the exhaust pipe. Exceeds the flow resistance determined by the pressure sensors 5 and 6 has a predetermined, depending on the type of used Filter and engine type, dependent value to be determined once for each engine and filter type, the engine brake consisting of the actuating device 9 and the throttle valve 10 is activated, the engine load increases and the soot on the soot burn-off filter burns off. The length of time the engine brake was applied, causing it to burn down of the filter is sufficient, must also be determined once for each engine type, but it can also, in particular when using two pressure sensors when using an engine brake or when using one Retarders or the vehicle brake can be individually controlled directly by the exhaust gas back pressure in front of the filter.

Durch das erfindungsgemäße Verfahren bzw. den Dieselmotor mit Rußabbrennfilter lassen sich auch Rußabbrennfilter bei Fahrzeugen, die überwiegend im Teillastbereich, z.B. im Stadtverkehr betrieben werden und daher die erforderliche Zündtemperatur des Rußabbrennfilters nur selten erreichen, sicher zünden, was immer zu einem freien Filter führt und damit stets die volle Motorleistung und einen niedrigen Teibstoffverbrauch gewährleistet.By the method according to the invention or the diesel engine Soot burn-off filters can also be used with soot burn-off filters for vehicles that are mainly operated in the partial load range, e.g. in city traffic and therefore the required Rarely reach the ignition temperature of the soot burn-off filter, ignite safely, whatever to a free one Filter leads and thus always guarantees full engine performance and low fuel consumption.
